USING FLASH CS4 PROFESSIONAL
Best practices
Testing your ads
Test your SWF file ad on the most common browsers, especially the browsers that your target audience uses. Some
users might not have Flash Player installed or they might have JavaScript disabled. Plan for these circumstances by
having a replacement (default) GIF image or other scenarios for these users. For more information on detecting Flash
Player, see “
Specify publish settings for SWF files
” on page
383. Give the user control of the SWF file. Let the user
control any audio in the ad. If the advertisement is a borderless SWF file that hovers over a web page, let the user close
the advertisement immediately and for the duration of the ad.

Optimizing FLA files for SWF output
Optimize Flash documents
As your document file size increases, so does its download time and playback speed. You can take several steps to
prepare your document for optimal playback. As part of the publishing process, Flash automatically performs some
optimization on documents. Before exporting a document, you can optimize it further by using various strategies to
reduce the file size. You can also compress a SWF file as you publish it. As you make changes, test your document by
running it on a variety of computers, operating systems, and Internet connections.
For a video tutorial about optimizing SWF files, see
www.adobe.com/go/vid0140
.
Optimize documents
Use symbols, animated or otherwise, for every element that appears more than once.
Use tweened animations whenever possible when creating animation sequences. Tweened animations use less file
space than a series of keyframes.
Use movie clips instead of graphic symbols for animation sequences.
Limit the area of change in each keyframe; make the action take place in as small an area as possible.
Avoid animating bitmap elements; use bitmap images as background or static elements.
Use mp3, the smallest sound format, whenever possible.
Optimize elements and lines
Group elements.
Use layers to separate elements that change during the animation from elements that do not.
Use Modify
> Shape
> Optimize to minimize the number of separate lines that are used to describe shapes.
Limit the number of special line types, such as dashed, dotted, ragged, and so on. Solid lines require less memory.
Lines created with the Pencil tool require less memory than brush strokes.
Optimize text and fonts
Limit the number of fonts and font styles. Use embedded fonts sparingly because they increase file size.
For Embed Fonts options, select only the characters needed instead of including the entire font.
